If your thermocouple is literally burning out, then have the pilot assembly checked and clean, check the orifice and the gas pressure to the pilot. Make sure the orifice size is correct for what type of fuel you are using (liquid propane or natural gas). Worst case you could have a gas valve or regulator going bad. Please have this done by a qualified service technician. I hope this helps.

If it is a 'standing pilot' furnace and it just 'went out'...I would think you need to try to re light the pilot light. If it doesn't re-light, it is probably time for new thermocouple. Presidentials are very tricky to install a thermocouple on if you are not experienced with it or if you don't feel comfortable working with gas and electricity.
Probably should call a local 'handy-man' at the least to perform the task or a local HVAC service company.
There should be a series of phillips head screws around the perimeter of a large access panel on the front of the furnace. You'll need a 3/8" wrench for the thermocouple connection to the gas valve and a 7/16" wrench to remove the 'pilot' line off of the gas control. Look for how the pilot assembly mounts under the pancake style burner because its much easier to remove the whole pilot assembly to replace the thermocouple than just it by itself. Once removed, it is self-explanatory as to replacement of the thermocouple.
Do NOT overtighten the thermocouple connection into the gas valve as you can damage the gas valve by doing so. Make sure you leak test the pilot tube connection after it is reconnected to the gas valve. A diluted solution of dishwashing liquid dashed around the ferrule of the pilot line should show bubbles if there is a leak. No gas will be in that line unless the pilot button is depressed and/or the pilot light is lit and burning.
Hello, this could be a problem with the thermocouple or gas valve. Start by replacing the thermocouple since it is very inexpensive, if that does not get it going sounds like the gas valve will need to be replaced
The Coleman Model # 130A , Above Ground Pool and Spa Heater was manufactured by Raypak for Coleman and several other companies, using the same Model Number. With that said, here is a link to the Owners Manual for Model # 130A. You can download and print it for future reference.
The Serial Number would really help in defining how old your Coleman furnace is. The model you have is used predominantly in manufactured housing. To find the Serial Number, you will need to remove the upper shroud of the furnace. There should be a sticker or plate on the back of that shroud of just inside the housing of the furnace, that will give you the Model # & Serial #. Armed with that, you can do a little detective work, as to it's age.
If you're using a 20lb propane tank (Gas Grill Tank), that may be the problem. Turn off the propane tank at the tank valve and disconnect it from the tank. Wait 5 minutes and reattach the heater hose to the tank. Turn the propane tank valve on very,very slowly until it's all the way open. Try lighting your heater now. If the pilot flame height returned to normal, that was the problem.
FYI - The Thermocouple has nothing to do with the length of the pilot flame. It's a safety feature that stops the gas if the pilot flame goes out for any reason.
Hope that solves your problem. Please let me know.
Sounds like the Thermocouple is going bad. Or, since it's Propane, he Thermocouple has a lacquered finish on it from the propane. If so, locate the Thermocouple (see your Owners Manual) and using a strip of fine sand paper, polish the Thermocouple thoroughly. You don't want to actually sand it, as much as polish it. Then wipe off the Thermocouple with a cotton ball soaked in alcohol. Allow the alcohol to evaporate before attempting to light the pilot.
Also your should trace the Thermocouple wire back to where it enters the control valve. Try loosening the nut with your fingers. If it does loosen, finger tighten it and with the appropriately sized open wrench, tighten it only a 1/4 turn more.
If either of the trouble shooting suggestions don't solve your problem, the Thermocouple will have to be replace. You can buy one directly from Coleman online. Make sure you have your Model # & Serial # before ordering.
